Transport Mechanisms
1. Cadmium (Cd) is a heavy metal that can have negative effects on the growth of plants. A group of scientists researched Cd uptake in plants by treating plants with different concentrations of Cd (0 mg, 20 mg and 40 mg). The graph shows the presence of Cd in different pathways in the plant roots after treatment. Note that the error bars show standard deviation.
Which of the following statements about the results of the study are correct?
1 | The size of the Cd dose does not significantly influence its concentration in plant root pathways |
2 | Cd in the symplast pathway is less likely to enter the xylem |
3 | After a 40 mg dose of Cd, the heavy metal is approximately 2.5x more likely to be present in the symplast pathway than the apoplast pathway |
4 | The soil in which the plants were grow contained Cd in a very low dose |
